atent to Cook and Kurtz, Number 789,528,- i ay 9, 1905', such type of plows being characterized by one'or more combined cultivat ing and "propelling tool s, preferably disks,

which are connected. with the frame and with a driving engine mounted on the frame so that the operation of said tools or dis'ks' both cultivates the groundand repels the apparatus over the same, and y adjustmentof the inclination of the axis or axes.

Inthe twoprior. patents mentioned above,

we have disclosed two or more pairs of gangs 2 of cultivating and propelling tools, the gangs of each pair being arranged to cross the line of movementof the plow oppositely to each other so that the disks or other tools act effectively on the earth to cultivate it, and

their opposite exerted side thrusts result in aipropellirlg effort directly ahead. In

those 'forms'ol our -invention one tool or mail t being propulsion-aheadI- aform of the invention in which the side thrust-or tendency of'one tool or gang of tools is resisted not by an opposing tool or gang of tools,'-but by a means or device which operatessomewhat-on the principle of the land side of acommgnplow, that is to say, by. engaging the earth and thus resisting lateral displacement of the plow without affecting, however, free forwardpropulsion thereof. In the preferred form voi my pres-;

ent invention thisnovel device for resisting lateral movement is in the form'of one or, moredisks which enter the earth and areadjustable to facilitate steeringthe' plow.

It may, however, assume various other forms, such, for example, as that of a continuous runner or plate which enters the.

gan of. tools works against the other, the.

earth to prevent lateral motion after ,the

manner of a keel of a marine vessel.

My present invention also relates to-certain improvements in the manner of disposing the propelling and cultivating disks, which only so that their axes cross the line of travel of the plowbutalso by dis osing the disks at an inclination to the sur ace of the ground, this resulting in a more pronounced pulverrzation of the earth. In adaptingthi's improvement thedisks thus inclined may be driven from separate trains of gears running respectively to'each disk, or by a universally jointed shaft, or'a'ny other device. suitable for the purpose.'- 1

The invention 'turesof major or'r'ninor importance, andall will. be fully ticularly pointed out in-thc claims. Reference-is'to be had to theaccompanying drawings which illustrate as examples several manners in which my presentinvention may be practically embodied and in which drawings Figure away; Fig. 2 is a transverse section taken through one of the gangs of disks; Fig, 3 is a d1agrammatic plan view illustrating-a modification in the means for adjusting thein 'clination of the propelling and cultivating tools and the land side device; and'Fig. A is a diagrammatic view illustrating a inodifica is to say, by arranging them not involves various other feaset forth hereinafter and par 1 is a plan vview with parts broken tion in the 'means for driving the inclined propelling and cultivating disks.

Referring first to Figs. 1 and 2, 10 indicates a frame carrying an engine or other source of hi present invention relates, however, to

- following elements, to wit,- a worm-wheel 16, fastened to the disk, a worm 17 fastened to the shaft 18 mounted 1n the corresponding bracket14 and connected by miter gears 19 and 20 to a driving shaft 21 which is rotata- 1 10 bly held in the tool frame 12. @Each tool frame'is provided with a fifth wheel ring or runner 22, and these are engaged with corresponding segments 23 fastened to or suitably mounted on the main frame 10. The shafts 21 are connected by miter gears 24 and 25 respectively with shafts 26 which are suitably mounted coincident to the centerof pivotal movement of the tool frames, and are in turn connected by gears 27 and 28 with the shaft 29 of the engine 11, so that positive rotar movement is imparted from said engine t rough the various transmission devices to the cultivating and propelling tools or disks 15. It willthus ap ear that the tool frames 12 carrying the too s or disks 15 are arranged. so that said disks engage the earth at an inclination to the surface thereof, and so that the tool frames may befreely adjusted around vertical centers to,

cause the axes of the tools 15 to extend at true right angles to the line of movement of the apparatus, orat any inclination thereto that may be desired. In the first osition rotation of the cultivator tools vn'l cause them to act simply as traction or propelling wheels, advancing the apparatus over the ground without plowing the same, while when the parts assume the second position rotation of the tools 15 from the -motor or engine will cause said tools not only to propel the apparatus over the earth but to effectually plow, harrow or otherwise cultivate the.

ground.

As here shown, the land side device is composed of two disks 30 which are arran ed at one side of the framev 10 and are suitably mounted on forks 31, the stems of which turn freely in vertical bearings 32 attached to the frame 10. These land-side disks 30 are intended to operate normally lying in a plane parallel to t ap aratus, and they are desi ned to enter to the stems of 'the forks 31 arms 33, said -With the toothed rings 35 worms 36. are

be ow the surface of' the 'eart so as effectually to'engage the same and enable them to resist lateral displacement of the 'plow in either direction. Said disks are ,mounted so that they may be turned around vertical centers 'to facilitate steering and otherwise manipulating the plow, and as shown i'n Fig. 1 the arts are so arranged that the land-side disks 30 are adjusted around vertical centers simultaneously 'with .and

corresponding to the adjustment of the tool frames 12. This is effected by connecting arms being adjustably connected as shown in Fig. 1 with links 34, and these links are in turn articulated to a part ,of the fifth wheel sections 22 or to some other part in secure connection with the tool frames .12. Said fifth wheel sections 22 also carry in rigid connection therewith toothed" rings 35, and

ally or otherwise rotating the shafts.

1e line of movement of the of tools to the lineof movement of the plow,

and that this adjustment of the tools results in a simultaneous and corresponding adjustment of the land-side disks 30 soas to facilitate steeringand turning the plow. also be observed that by providing an adjustable connection betweenthe links 34 and arms 33 I am enabled to adjust at will the relative inclination of the tool frames to the line of movement, thus enabling me readily to suit the apparatus to the various sorts of soil or to various other agricultural conditions.

If desired the inclinations of the cultivating and propelling tools and the land-side devices may be adjusted independently of each other, and not in unison, as in Fig. 1. To accomplish this change I provide the arrangement shown iliagrammatically in Fig. 3, in which two shafts 3-7 'and 37 are provided, these being provided with hand wheels 38 and 38 or any suitable means for manu- Said shafts carry Worms 36 and 36? in mesh with toothed members 35 and 35 respectively in connection with the gang or gangs of cultivating tools and the land-side disks, thus enabling the inclinations of. the tools to ,be changed at will independently of the adjustment in the inclination of the land-side disks.

In Fig. 2 I have illustrated a separate train or gearing for driving each cultivating disk. If desired, however, the universally jointed shaft arrangement shown in Fig. 4 may be provided. In this form of the inven-v tion the inclined cultivating and propelling disks 15 have their inclined axes oined by shaft sections 40 through the medium of universal joints or couplin s 41, and this com-- posite shaft is driven y a" single gear 42 which may be of any desired form. As here shown it is a sprocket chain and wheel arrangement connectedv with one end of the shaft. This device it will be seen avoids the clined disk.

Having thus described the preferred embodiment of my invention what I claim as new, and desire to secure by Letters Patent is:

I. A motor-plow-having a frame, a plowing tool joined thereto and serving, when in normal 0 eration, to exert a ropelling influence a ong a line at ,an-inclmation to the normal line of movement of the plow, an en-' gine mounted on the frame and connected It will with the said tool positively to drive the same, a land side'device connected to the frame and serving when in normal operation, to engage the ground in a plane substantially parallel to said normal line of movement of the plow, to resist the lateral pro elling action of said tool and to cause the p ow to advance on its said normal line of movementand a mechanism connected to said plowing tool and land side device, for changing the positions of the same with respect to theline of movement of the plow whereby 'to steer the plow.-

2.
